Criminals can run, but they can't hide forever. Like Johnny Cash sang, "what's done in the dark will be brought to the light." Eventually, the poop of rogue poopers catches up with them.

For some dog owners, scooping up poop is just too much work. This can be a serious problem at apartment complexes. That's why some property managers in Knoxville, Tennessee are resorting to DNA testing to enforce poop scooping rules:

Apartment managers start by sending in a DNA sample from every dog in the complex, usually on a swab that has been swiped in the dog's mouth. The DNA is recorded on a PooPrints registry.

Then, when an errant stool is discovered, a sample is sent in and matched with the DNA in the database. The renegade pooch and owner are identified.
